Rescuers were called out to find a walker tackling the Yorkshire Three Peaks Challenge after he got lost in the dark.
The Clapham-based Cave Rescue Organisation was alerted by police about 11.10pm on Saturday after the 38-year-old walker called 999 to say he was disoriented on Ingleborough.
The man told rescuers he had no torch and could only tell them he was in a limestone area.
A team spokesperson said: “Unfortunately his phone signal was lost before further information could be obtained.
“Search teams were deployed up from Horton in Ribblesdale and into the Sulber and Nick Pot area. He was found by one of the teams near Horton Quarry, above Beecroft Hall, and escorted down to the village.
“He had been doing the Three Peaks walk with three companions before becoming separated and going off route. They were all located safe and well in Horton.”
It was the second Yorkshire Three Peaks rescue of the day for the volunteer team.
About 10am it received a call after a fellrunner attempting the 39km (24-mile) route.
The 47-year-old man had slipped coming down from Pen-y-ghent summit and suffered a suspected broken ankle.
Marshals who were on the hill for a challenge walk treated him initially before CRO members met him near Hunt Pot.
A team spokesperson said: “Following examination the casualty was transported by team vehicle down to a road ambulance waiting in Horton in Ribblesdale. An air ambulance also attended.”
The CRO carries out rescues both in the caves and potholes and on the fells of the Yorkshire Dales.
